Dante & Networked-Audio Principles: Routing, Timing & Clock Sync

Est. 55 minCompetency: Explain Dante routing, clocking, and networked-audio principles.

Learning objectives

Explain Dante audio networking at a high level.
Describe device discovery and routing.
Explain clock synchronization and its importance.
Identify Dante network requirements.

Vocabulary

Dante: A networked-audio standard using standard Ethernet; routes audio over IP.
Device discovery: Finding Dante devices on the network using the controller.
Clock sync: A shared timing reference that keeps devices sample-accurate.
Latency: Delay through the network; Dante sets a network latency.
Subscription: Routing a Dante transmitter to a receiver.

Lesson content

Dante moves audio over standard Ethernet instead of analog cables. A DSP input, a stagebox, an amplifier, and a codec can all be Dante endpoints on one network.

How Dante works

Each Dante device is a network node with transmit and receive channels.
A Dante controller discovers devices and routes channels by subscription.
Latency is chosen at the network level; lower latency needs a faster, cleaner network.
Clock sync keeps all devices sample-accurate; one device is the clock master.

Clocking

1Dante devices share a clock; one is elected clock master.
2A stable clock prevents clicks, dropouts, and drift.
3Use a good clock master (a stable DSP or a dedicated clock) and let the rest follow.

Network requirements

1 Gb switches for most Dante; disable energy-efficient Ethernet (EEE) which can cause dropouts.
Use IGMP snooping for multicast Dante traffic.
Keep Dante on its own VLAN; avoid mixing with high-burst data.

Field caution — EEE

Energy-Efficient Ethernet (EEE/802.3az) can cause Dante dropouts because ports sleep between bursts. Disable it on Dante switch ports.

Worked example

A conference room: a Dante-enabled DSP is clock master. Ceiling mics, a codec, and an amp are Dante endpoints. The controller routes mic channels to the DSP and DSP outputs to the amp — all over one 1 Gb VLAN with EEE disabled.

Implementation checklist

✓Dante devices discovered and named.
✓Routes set by subscription in the controller.
✓Stable clock master chosen.
✓1 Gb switches, EEE disabled, IGMP snooping on.
